This Powerpoint introduces prime and composite numbers, mirroring the 7-steps strategy. Beginning with prime numbers, a definition and some examples are included. These examples include arrays to appeal to the visual learners as well. Then, some non-examples of prime numbers are included. This is a perfect transition into the slides on composite numbers. Again, the definition and an example is included. For both prime and composite numbers, an interactive sentence stem is built in to give students practice with both of these numbers.
